To all whom it mayconcem: clamped to theshaft3. fine end of said -oord 6 is connected with one of said dogs 'by thespring 9. The pulley 10 is fixed to the shaft 3 and is driven h the belt11. 12 is a notch in the face of t o hub of the pulley l0, wluch notchis inclined at one side only. 13 Is a pm pressed forward by the spring14 into said notch and serving tohold the shaft.3- from rotation as wireis drawn ofi" the spool 1 and thus insure that the drawing oil of thewire therefrom shall be resisted by the friction on the wheel 5. This in18 also acts to prevent the improper 'vmg of the shaft 3 from thereversing mechanism but permits said shaft to revolve in the 0 positsdirection to reverse the direction of t e rotation of the s 001 1, as

will be set forth hereinafter, to ackwind' 3'is ns de by the two dis s15 and 16, and the interposed r0 e or other friction material 17. Thedis 15 is fixed a rota:

tion on the shaft'3 by a pin 1 cxtendin a from the shaft into alongitudinal slot '1 connection between the spindle 2 andshaft in thehub of'said disk. 20 is the collar of the shifter by which the disk 15is given its longitudinal movement. The disk 16 is free to. rotate uponthe shaft 8 but is secured ainst longitudinal movement v thereon by t ecollar-.21 fixed to the end of said shaft.

16- is a ball thrust bearing between the disk 16 and collar 21 and 16"is a similar bearin between disk 15 and c0llar 20. The pin 2 connectsthe disk 16 with the disk 23 fixed to the spindle 2 so that the. disk16are rotatably fixed to each other.

24.- is the shifter-lever engaging the collar 20 and which ic-oscillated by pin 25 in the oscillating hub 26. For oscillating thishub, the arm 27 is fixed thereto and carried thereby, said arm Eludewheel 28. 29 is a fixed guide-wheel. 3T e-wire'extends from they spool'1 around the guide-wheel 29 spindle '2 and upward as f v and thencearound the guide-wheel 28 and the connections described a corr endingvariation in the degree of-irictlon tween the dislis .15 and 16. 28' isa spring to check theguide-wheel'28 until the tension reaches "anyvariation in" the-tension'pf: this'wire produces acorrespondingvariation-1n the =position0fthe'g1'11de-wheel 28 and through adetermined pint; The construction Shown in Fig and 11, therefore, an

plies an automatic re ator whereby t e tension mechanism actm upon thesupplyspool is automatically a justed to compensate for any variation oftension .due to other causes, such as the change in diameter also servesas a drivin of the coil of wire upon the spool as the winding therefromprogresses. The friction engagement between the disks 15, 16,

connection or engagement between the afts 3 and 2, to re- I .verse therevolution of the spool 1, when the'shaft 3 is revolved as hereinafterset forth. It will be understood that the pin 13 may also be employed inthis formof tension mechanism to hold the shaft 8 against rotation whenthe spool 1 is paying outthe the guide-wheel under its tensionthroughout a wide range. The strength of the spring willbe dependentupon the wire be'ing woundbut should be such as to permit theguide-wheel 30 to yield promptly to all variations of tension whichwould cause the stretching or breaking of the .wire being wound. Theyieldingguide B may be referred to as a secondary tension mechanism andthe supply-spool-tension mechanisrh as a primarv tension mechanism.

The crime mechanism C may be described in detail as follows: 36 is abracket upon which is journaled the wheel 37 in approxi-. mately thesameplane with the wheel 30, and, also, the wheel 38 in a planeapproximately at right angles thereto. parts 89sand 40 togetl1er form atelescoping column, the post 39 being provided with threads designed toco-act with similar threads formed on the interior surface of the post40, while 41 is a thumb nut or 001- lar carried by the post 40 for thepurpose of enabling the post tobeadiusted rela-- tively to the part 89with faoilityund convemence. On top of this column is mounted the wheel42 approximately in the same plane with the wheel38. The column part v{0 is provided with the lugs ifiand 44, be- 'tween centers connectedwith which the crane member is' mounted. On top ofthis crane member ismounted the wheel 46 and the crane member is provided with the frontlugs 47, 48, between centers connected with which is pivoted the cranemember 49 The two' on to of which mounted the guide-wheel 50. helocationis such that theaxis of the pivotal connection at the lugs 43and 44 r is substantially tangentto. the two wheels :42 and 46 and theaxis of the pivotal connection at the lugs '47 and 4851s Substun tiallytangent to. the twowh 1e46- and 50.

Therefore, the strand of wt being wound passes these two pivotalconnections with out any substantial variatio' in length or directionfor crane."

The. crane-steadyina' mechanism l consist of the following; details: Tothe bottom of the crane-member 49 is secured oil, contained int-hecircular receptacle 51.

which is supported by a post 52'capable of being fixed at variousvertical adjustments by the set screw-53. Bythis or other suit- .ablemeans the movements of the thread guide are deadened; or, in otherwords, re

tarded against erratic movements.

.Thespln e-meclmuism-E colnprlses the tail-stock 54 and headstock 55adapted to center the core of the bobbin or coil receiver 56 and drivenby the belt 57 from the pulley 58. 59 is thewiuding-guide supported onthe forward end of the crane part-"Q9, and 60 is a guide-wheel acting asa. lehder to said winding' g'uid. The wining-guide 59 is maintained bythe crane in such positionbelow the bobbin that the strand of wirerunning from it tothe bobbin? is substan-;

tially vertical and also that the winding guide fitland its leaderfio'will-just clear the heads of the bobbin in the traversing movements.The requisite adjustment for this purpose is afforded by the alreadyreferred to telescopic post 39, 40 and the adjustable support of thereceptacle 51.

The controlling mechanism F-may be described in detail as follows: 61 isa shaft supportedin hangers 62 beneath thetable andsplined-to itsdouble-acting clutch 63 controlled by the shifting lever 64.. On oneside. this clutch engages with the pulley 65 revolving freely onsaidshaft. 0n the other sideysaid clutch. engages with the pulley 66aiso'frec to revolve on saidsheftand which, in turn, frictionall yeiikages with the pulley 67 also free to revolve on'said shaft. 68 and69 are spiral springs interposed between said clutch and each of itsadjacent pulleys. 58 is a pulley fixed to said shaft. The pulley 65 isconnected byfthe belt 71- with the pulley 72 on line shaft 5*73 so thatwhen said clutch engages with said pulley 65 the shaft 61 -is,-drivenfrom the line shaft in the direct-ion to wind. The pulley 66 isconnected by the crossed belt '74 with the pulley 75' on the lineshaft.73,rso that when the clutch is in engagement withthe pulleymovement by reason of the presence of the. spring 69 will be tofrictionally connect the 66 the shaft 61 is driven in the direction forunwinding; The pulle" 67iis connected by the belt 11 with the p11 ey' ofthe tension mechanism. v .The pullev 58 is connected by the belt 57 withthe pulley 77 of the spindle mechanism, When, new, the clutch 63 ismoved to .the left, the firstelfect of said driving engagement betweensaid pulley 10 and the spec 1. The next effect will be to compress thespring 69 so as to frictionally engage the clutch with the pulley 66 andthus start the shaft 61 and the spindle-pulley 77 in unwindingdirection. In this way, it is insured that the movement of thetensionmechanism will pre'cede the unwinding movement of the spindle andthereby prevent the production of any slack such as could not be takenup. by the spring and might cause the wire being woundto be dis-vmounted from its guide-wheels.

To facilitate the threading or placing of the wire being wound upon thevarious guide-wheels, said wheels are arranged to overhang theirbearings, showmand the flange of the wheel next its bearing is madedeeper than the other flange. For example, the wheel 46 overhan itsbearing 78 and its flange 79 is deeper on its flange .80. .To. preventthe spring 35 from causing the unthreading of the wire during thedianging of the bobbins, I provide the pair of clamp spring 35 yieldssufiicientl ing disksSl pressed together by the nut 82,

bet-ween which disks the wire passes and by which the operator can,cause it y to be clamped and old by setting up the'nut 82 preparatory tocutting thewirejfor chang ing the bobbin.

The operation is as follows: The machine being threaded for winding, theoperator moves the clutch 63 into engagement with, the pulley 65 and thewindmgsterts. The to prevent the breaking or stretching of e wire unt lthe supply-spool 1 gets under way. If the form of tension mechanismshown in Figs. 6 and 7 be employed the operator by movement of the dogs7 and 8 onthe shaft 3' produces the "requisite pressure and are ofcontact by the cord 6 to roduce the desired tension and changes thisadjustment from time to time as the winding roceeds to make the tensionconform to the lessened diameter of the coil remaining on thesupply-spool. If, however, the form of tension m I shown in Figs. 10 and11, be employed thls ad ustment is performed automatically. As thewinding proceeds, the crane supports the axis of the winding guide 59 inahorizontal plane but permits itsv movements in that plane to be freelyand solely controlledby the strand of wire being wound. .Said

strand controls the movement. of the winding guide, not, merely during.eachltraverse across the bobbin, but also byjitsjflcontact with thehead of-the bobbin determines; when .the vibration of the supportingtable.

Should the operator discover any irregular-ity in the winding he canreverse the operation by throwing the clutch 63 in theop: positedirection to engage the pulleys 66,67, asheretofore set forth and thuscause the wire to he wound from the bobbin back onto the supply-spoolagain.

It will be understood that the tension mechanism, whether it be oftheform shown in Figs. 6 and 7 or Figs. 10 and 11, operates to maintain theproper tension in the strand. When the wire is aying out to be wound onthe coil receiver-t e.tension mechanism returds; rotation of the supplyspool so that the proper tension is maintained for the strand, and-whenthe pulley 10 is revolved to rotate the supply spool to draw thewirefrom the coil receiver, thefrictional connection, irrespective ofwhich form is em' loyed,

between the. shaft 3 and the shaft 2, orms a slipping. connectionbetween said shafts so "that thewinding of the wire on the spool 1cannotplace the wire under too high tension as the shaft 1 will sliprelative to the shaft 3 shouldthe tension in the strand become too high,and it will therefore be seen that the tension mechanism during thebackwinding operates to prevent excessive tension.

All. of the guides for the wire and the moving supports for said guidesshall be constructed as 1i ht us is] consistent with strength and stiuses, such as the guide wheels 80, 37 38, 42, 16, 50, 59 and 60, and thecrane members flfi and 49;

Having thus described my invention, I claim-as new and desire to secureby Letters Patent by the guide may have traversing movements .in a rightline parallel to the axis of the coil receiver, which movements aresubstantially free to be controlled by pull of the strand being wound,and fluid means for retarding the movement of the-guide.
